When my youngest daughter was about 7, she would help me wash my motorcycle in the garage. She would throw on my helmet and jump on the back and just sit there as I would polish the chrome. One day, I turned on the bike and took her on a quick ride down the alley. I went about 5 houses down and turned back.
Our top speed was a neck-breaking 4mph. She absolutely loved it. We made it our secret. And I had her change clothes immediately so her mom wouldn’t smell the exhaust. We finally told her mom when my daughter turned about 13. She’s now 18 and still jumps on the back as often as possible.
